I'm looking for a network specialist to interconnect two networks with Cisco / Mikrotik or better proposal. Let me explain the attached file where you can check the problem and the goal I would like you can reach.
Currently we have connected 4 offices in different cities throught private network of ISP Y. All offices can reach servers in city A. I can't check routing information inside the cisco routers in any office, due to the fact that routers belong to ISP Y, besides ISP Y takes too long to give me information about configuration or support when we have problems with interconnection between offices. So we decided to change to ISP X who would give us the service of interconnection between our offices. But there is a problem, City D is far away, so ISP X would take around 2 months to place its router in city D. In cities A, B and C, ISP X have alredy setup its router, so we could migrate city A, B and C and they would be interconnected between them. Nevetheless, as City D is going to take 2 months to have a router from ISP X, we are thinking to keep service with ISP Y so that City D can reach main office in city A where are the servers. But when packets arrives from city D to city A, they would be looking for ips of servers, but servers are in network of ISP X. By the way, routers from ISP X and ISP Y on city A are in the same room.
I can't connect a cable between switch of ISP X and ISP Y, due to the fact that I would have 2 gateway with the same ip address 10.1.10.1. Besides, I can't make any change on routers of ISP Y, as I said, they have very very bad support, they would take years to add a static route.
My idea to interconnect both networks and make possible that City D can reach servers on Network of ISP X woudl be the following:
Configure router mikrotik 1 with ip of the servers, resend packet to next step (Router mikrotik 2) and then introduce packet to the network where servers are. In routers of ISP X, it's possible to ask ISP X to add a static route so that servers can reach network in city D 10.4.0.0/16
Another idea would be to access to router cisco from ISP Y in City A and change routing, but I don't have password of the router, as I say, it belongs to isp Y. But if you know how you can access to router and change routing, it would solve the issue soon.
In summary, I need a networks experienced specialist who can make office in City D reach servers in City A taking into account the drawbacks I explained previously. By the way, I just gave some ideas to solve the issue, don't know if it would work well, but if you have a better proposal let me know.
